Embodiment 1

[0015] Example 1: Toxicity test of methoxyfenozide and chlorpyrifos

[0016] The compound test of methoxyfenozide and chlorpyrifos uses cotton bollworm as the test object. The specific method is:

[0017] Cotton bollworm (Helicoverpa armigera Hubner): The original drug of the test, methoxyfenozide, was from Dow AgroSciences, and the original drug of chlorpyrifos was from Nanjing Red Sun Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test insects were collected from Xiantao, Hubei, and the third-generation third-instar larvae were raised indoors with artificial feed for the test. The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.14-2006". Soak cabbage leaves of one size to one in the medicinal solution at a series concentration for 5 seconds, take them out to dry, and put them in a petri di...

Embodiment 2

[0026] Embodiment 2: Methoxyfenozide and phoxim toxicity test

[0027] The compound synergistic test of methoxyfenozide and phoxim, using beet armyworm on vegetables as the test object. The specific method is:

[0028] Beet armyworm (Laphygma exigua Hubner): The original drug of the test, methoxyfenozide, was from Dow AgroSciences, and the original drug of phoxim was from Nanjing Red Sun Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test insects were collected from Xixiang, Baoan, Shenzhen. Three generations were raised with artificial diet, and the third instar larvae were used for the experiment. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.14-2008" and "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and adopts the leaf soaking method. Soak the cabbage leaves in the medicinal solution for 5 seconds, take them out and dry them, ...

Embodiment 3

[0033] Embodiment 3: Methoxyfenozide and triazophos toxicity test

[0034] The compound synergistic test of methoxyfenozide and triazophos uses the larvae of Chilo suppressalis as the test object. The original drug of azophos was from Zhejiang Xinnong Chemical Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.11-2008" and "The People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and adopts the rice stem dipping method. A 10cm-long rice stem was soaked in the medicinal solution for 5 seconds, compared to soaked in clear water, taken out and dried, then put into a large test tube, and each large test tube was inserted with 5 third-instar larvae of Chilo suppressalis. Check the results after 72 hours. The inspection results, data processing and toxicity evaluation methods are the same as those in Exampl...

Abstract

The invention discloses a pesticide composition and application thereof in agriculture. The effective components of the composition contain methoxyfenozide and organophosphorus pesticide, and the massratio of methoxyfenozide and organophosphorus pesticide is 100:1 to 1:100. The pesticide composition has the advantages of synergism, quick action and long effect, can reduce the use amount and savelabor, and is also good for delaying the development of resistance. The pesticide composition can be used for preventing and treating pests in plants, and is particularly suitable for preventing and treating lepidoptera pests such as spodoptera exigua, prodenia litura, cnaphalocrocis medinalis guenee, chilo suppressalis and cotton bollworm.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to a pesticide composition containing methoxyfenozide, which is used to prevent and control pests on plants. Background technique [0002] Among insecticides and pesticides, organophosphorus pesticides are an important class. This kind of insecticide has been one of the main categories of pesticides since the 1960s due to its wide application range, good efficacy, and various modes of action. The long-term and large-scale use of organophosphorus has brought about a series of problems such as drug resistance, human and animal poisoning, excessive pesticide residues in agricultural products, and environmental pollution. However, due to its advantages of broad spectrum and low price, organophosphorus pesticides still occupy the first place in the amount of pesticides used in my country. The gradual replacement or partial replacement of organophosphorus pesticides is ...
